The February 26 Incident(二・二六事件,Niniroku Jiken?) (also known as the 2-26 Incident) was an attempted coup d'état in Japan on 26 February 1936. It was organized by a group of young Imperial Japanese Army (IJA) officers with the goal of purging the government and military leadership of their factional rivals and ideological opponents.

Although the rebels succeeded in assassinating several leading officials (including two former prime ministers) and in occupying the government center of Tokyo, they failed to assassinate Prime Minister Keisuke Okada or secure control of the Imperial Palace. Their supporters in the army made attempts to capitalize on their actions, but divisions within the military, combined with Imperial anger at the coup, meant they were unable to achieve a change of government. Facing overwhelming opposition as the army moved against them, the rebels surrendered on 29 February.[3]

Unlike earlier examples of political violence by young officers, the coup attempt had severe consequences. After a series of closed trials, 19 of the uprising's leaders were executed for mutiny and another 40 imprisoned. The radical Kōdō-ha faction lost its influence within the army, the period of "government by assassination" came to a close, and the military increased its control over the civilian government.

The Imperial Japanese Army had a long history of factionalism among its high-ranking officers, originally stemming from domainal rivalries in the Meiji period. By the early 1930s, officers in the high command had become split into two main informal groups: the Kōdō-ha "Imperial Way" faction led by Gen. Araki Sadao and his ally Gen. Jinzaburō Mazaki and the Tōsei-ha "Control" faction identified with Gen. Tetsuzan Nagata.[4][5][6]

The Kōdō-ha emphasized the importance of Japanese culture, spiritual purity over material quality, and the need to attack the Soviet Union (Hokushin-ron) while the Tōsei-ha officers, who were strongly influenced by the ideas of the contemporary German general staff, supported central economic and military planning (total war theory), technological modernization, mechanization, and expansion within China (Nanshin-ron). The Kōdō-ha was dominant in the army during Araki's tenure as Minister of War from 1931 to 1934, occupying most significant staff positions, but many of its members were replaced by Tōsei-ha officers following Araki's resignation.[7][8]

Army officers were divided between those whose education had ended at the Army Academy (a secondary school) and those who had advanced on to the prestigious Army War College. The latter group formed the elite of the officer corps, while officers of the former group were effectively barred by tradition from advancement to staff positions. A number of these lesser-privileged officers formed the army's contribution to the young, highly politicized group often referred to as the "young officers" (青年将校,seinen shōkō?).[9][10]

The young officers believed that the problems facing the nation were the result of Japan straying from the "kokutai" (国体?) (an amorphous term often translated as "national polity", it roughly signifies the relationship between the Emperor and the state). The "privileged classes" exploited the people, leading to widespread poverty in rural areas, and deceived the Emperor, usurping his power and weakening Japan. The solution, they believed, was a "Shōwa Restoration" modeled on the Meiji Restoration of 70 years earlier. By rising up and destroying the "evil advisers around the Throne", the officers would enable the Emperor to re-establish his authority. The Emperor would then purge Western ideas and those who exploited the people, restoring prosperity to the nation. These beliefs were strongly influenced by contemporary nationalist thought, especially the political philosophy of the former socialist Ikki Kita.[11]

The loose-knit group varied in size, but is estimated to have had roughly a hundred regular members, mostly officers in the Tokyo area. Its informal leader was Mitsugi (Zei) Nishida. Nishida, a former army lieutenant and disciple of Kita, had become a prominent member of the civilian nationalist societies that proliferated from the late 1920s. Nishida referred to the army group as the Kokutai Genri-ha (国体原理派,"National Principle"?) faction. Involved to at least some extent in most of the political violence of the period, following the March and October Incidents of 1931, the army and navy members of the group split and largely ended their association with civilian nationalists.[12][13][14]

Despite its relatively small size, the faction was influential, due in no small part to the threat it posed. It had sympathizers among the general staff and imperial family, most notably Prince Chichibu, the Emperor's brother (and, until 1933, heir), who was friends with Nishida and other Kokutai Genri-ha leaders. Despite being fiercely anti-capitalist, it had also managed to secure irregular funding from zaibatsu leaders who hoped to shield themselves.[15]

The exact nature of the relationship between the Kōdō-ha and the Kokutai Genri-ha is complicated. The two factions are often treated as the same or as two groups forming a larger whole. Contemporary accounts and the writings of members of the two groups make clear they were actually distinct groups in a mutually beneficial alliance, however. The Kōdō-ha shielded the Kokutai Genri-ha and provided it with access while they in exchange benefited from their perceived ability to restrain the radical officers.[16][17][18]

The years leading up to the February 26 Incident were marked by a series of outbursts of violence by the young officers and their fellow nationalists against their political opponents. Most notably, in the May 15 Incident of 1932 young naval officers assassinated Prime Minister Inukai Tsuyoshi. This incident is significant because it convinced the young army officers (who were aware of, but not involved in the attack) of the need to utilize troops in any potential coup attempt. The ringleaders of the incident, as in the previous March and October incidents, received relatively light punishments.[19]

The direct prelude to the coup, however, was the 1934 Military Academy Incident (November Incident) and its consequences. In this incident Capt. Takaji Muranaka and Capt. Asaichi Isobe, prominent members of the Kokutai Genri-ha, were arrested for planning a coup with a group of military cadets. Muranaka and Isobe admitted discussing such a coup, but denied having any plans to actually carry it out. The military court investigating the incident found there was insufficient evidence to indict, but Muranaka and Isobe were suspended by the army. The two were convinced that the incident was a Tōsei-ha attack on the young officers and began circulating a pamphlet calling for a "housecleaning" of the army and naming Nagata as the "chief villain". They were then expelled from the army.[20][21][22]

It was at this time that the last Kōdō-ha officer in a prominent position, Gen. Mazaki, was forced from office. The young officers were enraged by Mazaki's removal because, having become disillusioned with Araki for his failures to overcome resistance in the cabinet during his time as War Minister, Mazaki had become the focus of their hopes. Muranaka and Isobe released a new pamphlet attacking Nagata for the dismissal, as did Nishida.[23][24][25]

On 12 August 1935, in the "Aizawa Incident", Lt. Colonel Saburō Aizawa, a member of the Kokutai Genri-ha and a friend of Mazaki, murdered Nagata in his office in retaliation. Aizawa's public trial (which began in late January 1936) became a media sensation as Aizawa and the Kokutai Genri-ha leadership, in collusion with the judges, turned it into a soapbox from which their ideology could be broadcast. Aizawa's supporters in the mass media praised Aizawa's "morality and patriotism", and Aizawa himself came to be seen as "a simple soldier who sought only to reform the army and the nation according to the true National Principle."[26][27]

The Kokutai Genri-ha had long supported a violent uprising against the government. The decision to finally act in February 1936 was caused by two factors. The first was the decision announced in December 1935 to transfer the 1st Division, to which most of the Kokutai Genri-ha's officers belonged, to Manchuria in the spring. This meant that if the officers did not strike before then, any possible action would be delayed by years. The second was Aizawa's trial. The impact of Aizawa's actions had impressed the officers, and they believed that by acting while his trial was still going on, they could take advantage of the favorable public opinion it was causing.[28][29]

The decision to act was initially opposed by Nishida and Kita when they learned of it. The two men's relationship with most of the officers had become relatively distant in the years leading up to the uprising, and they were against direct action. However, once it was clear that the officers were determined to act anyway, they moved to support them. Another barrier to be overcome was opposition to the involvement of troops from Teruzō Andō, who had sworn an oath to his commander not to involve his men in any direct action. Andō's position in the 3rd Infantry Regiment (the largest source of troops) was essential to the plot, so Muranaka and Nonaka spoke with him repeatedly, ultimately wearing down his resistance.[30][31]

The date February 26 was chosen because the officers had been able to arrange to have themselves and their allies serve as duty officers on that date, facilitating their access to arms and ammunition. The date also allowed Mazaki to testify at Aizawa's trial as scheduled on the 25th.[32][33][34]

The uprising was planned in a series of meetings held between the 18 and 22 February by Mitsugi Nishida, Yasuhide Kurihara, Teruzō Andō, Hisashi Kōno, Takaji Muranaka, and Asaichi Isobe. The plan decided upon was relatively simple. The officers would assassinate the most prominent enemies of the kokutai, secure control of the administrative center of the capital and the Imperial Palace, and then submit their demands (the dismissal of certain officers and the appointment of a new cabinet led by Mazaki). They had no longer term goals, believing that those should be left to the Emperor. It is believed that they were prepared to replace Hirohito with Prince Chichibu if necessary, however.[35]

The young officers believed they had at least tacit approval for their uprising from a number of important army officers after making a number of informal approaches. These included Minister of War Yoshiyuki Kawashima, Araki, Mazaki, Tomoyuki Yamashita, Kanji Ishiwara, Shigeru Honjō, and their own immediate commanders, Kōhei Kashii and Takeo Hori. Kawashima's successor as Minister of War later remarked that if all the officers who had supported the rebels had been forced to resign, there wouldn't have been enough high-ranking officers left to replace them.[36][37]

They prepared an explanation of their intentions and grievances in a document, entitled "Manifesto of the Uprising" (蹶起趣意書,Kekki Shuisho?), which they wanted to be handed to the Emperor. The document was prepared by Muranaka, but written in Shirō Nonaka's name as he was the highest-ranking officer involved in the plot. The document was entirely in line with Kokutai Genri-ha ideals, blaming the genrō, political leaders, military factions, zaibatsu, bureaucrats, and political parties for endangering the kokutai through their selfishness and disrespect for the Emperor and asserting the need for direct action:[38][39]

Now, as we are faced with great emergencies both foreign and domestic, if we do not execute the disloyal and unrighteous who threaten the kokutai, if we do not cut away the villains who obstruct the Emperor's authority, who block the Restoration, the Imperial plan for our nation will come to nothing [...] To cut away the evil ministers and military factions near the Emperor and destroy their heart: that is our duty and we will complete it.[40]

Seven targets were chosen for assassination for "threatening the kokutai":

Support for the "organ theory" of the kokutai, refusal to resign despite his unsuitability.

The first four mentioned in the above list survived the attempted coup. Saionji, Saitō, Suzuki, and Makino were targeted because they were the most influential Imperial advisers. Okada and Takahashi were moderate political leaders who had worked to restrain the military. Finally, Watanabe was targeted as a member of the Tōsei-ha and because he had been involved with Mazaki's removal.[42][43]

Saionji's name was ultimately removed from the list, though the reasons why are disputed. Some of the officers' allies argued that he should be left alive to be used to help convince the Emperor to appoint Mazaki as Prime Minister, and this is commonly given as the reason. However, Isobe testified later that he had rejected these suggestions and continued to make arrangements for the attack on Saionji. According to his account, the attack was only canceled after the officers assigned to carry it out (teachers at a military school in Toyohashi) could not agree over the use of cadets in the operation.[44][45]

From the 22nd on, the 7 leaders managed to convince 18 other officers to join the uprising with varying degrees of enthusiasm. Non-commissioned officers (NCO) were informed on the night of the 25th, hours before the attacks started. Although the officers insisted that all NCOs participated voluntarily and any orders given were merely pro forma, many of the NCOs argued later that they had been in no real position to refuse to participate. The soldiers themselves, 70% of whom were less than a month out of basic training, were not told anything before the coup began, though many were (according to the officers) enthusiastic once the uprising began.[46][47]

Flag used by rebel troops during the uprising: "Revere the Emperor, Destroy the Traitors"

The bulk of the army was made up of men from the 1st Division's 1st Infantry Regiment (11th and MG companies; 456 men) and 3rd Infantry Regiment (1st, 3rd, 6th, 7th, 10th, and MG companies; 937 men). The only other significant contribution was 138 men from the 3rd Imperial Guard Regiment. Including officers, civilians, and men from other units, the total size of the Righteous Army was 1,558 men. An official count of 1,483 was given at the time; this number excludes the 75 men who participated in Nakahashi's attempt to secure the Palace (see below).[48]

The leadership adopted the name "Righteous Army" (義軍,gigun?) for this force and the password "Revere the Emperor, Destroy the Traitors" (尊皇討奸,Sonnō Tōkan?), adopted from the Meiji Restoration-era slogan, "Revere the Emperor, Destroy the Shogunate". Allies were also to display a 3 sen postage stamp when approaching the army's lines.[49][50]

It snowed heavily on the night of the 25th, covering Tokyo. This heartened the rebel officers because it reminded them of the 1860 Sakuradamon Incident in which shishi assassinated Ii Naosuke, the chief adviser to the Shogun, in the name of the Emperor.[51]

The rebel troops, divided up into 6 groups, assembled their troops and left their barracks between 03:30 and 04:00. The attacks on Okada, Takahashi, Suzuki, Saito, the Ministry of War, and police headquarters occurred approximately simultaneously at 05:00.[52]

The attack on Okada consisted of 280 men from the 1st Infantry Regiment led by 1st Lt. Yasuhide Kurihara.[53]

The troops surrounded the Prime Minister's residence and forced its guards to open the gates. Upon entering the compound and attempting the find the Prime Minister, however, they were fired upon by four policemen. All four were killed after wounding six of the rebel soldiers, but the gunfire succeeded in warning Okada of the danger. He was spirited into hiding by his brother-in-law, Col. Denzō Matsuo. Matsuo, who was said to have resembled Okada, was then discovered and killed by the troops. The soldiers compared Matsuo's wounded face to a picture of the Prime Minister and concluded that they had succeeded in their mission. Okada would escape the next day, but this fact was kept a secret and he played no further role in the incident.[54]

After Matsuo's death, Kurihara's men assumed guard positions around the compound. They were joined by 60 men from the 3rd Imperial Guard (see below).[55]

Kiyosada Kōda, accompanied by Muranaka, Isobe, and others, led 160 men to seize control of the Minister of War's residence, the Minister of War itself, and the General Staff Office. Once this had been accomplished, they entered the residence and asked to see Minister of War Yoshiyuki Kawashima. When they were admitted to see him at 06:30, they read their manifesto aloud and handed him a document in which they made numerous demands of the army, including:

The rapid resolution of the situation by Kawashima in a way that "advanced the cause of the Restoration"

The immediate dismissal of Lt. Col. Akira Mutō, Col. Hiroshi Nemoto, and Major Tadashi Katakura from the army for promoting "factionalism"

The appointment of Araki as the new commander of the Kwantung Army.[56][57]

As Minister of War (1924–27, 1929–31), Ugaki had overseen a reduction in size and modernization of the army. He had also failed to back the March Incident plotters (who had hoped to make him Prime Minister). Minami, Muto, Nemoto, and Katakura were all prominent members of the Tōsei-ha faction. Katakura was also partly responsible for reporting the Military Academy Incident. When Isobe encountered him outside the Ministry of War later that morning, he shot him (non-fatally) in the head.[58][59]

During this period, a number of officers sympathetic to the rebels were admitted, including generals Mazaki, Tomoyuki Yamashita, Ryū Saitō, and the Vice-Minister of War, Motoo Furushō. Saitō praised the young officers' spirit and urged Kawashima to accept their demands. Shortly before 09:00, Kawashima stated that he needed to speak with the Emperor and left for the palace.[60][61]

Capt. Hisashi Kōno commanded a team consisting of 7 members, including 6 civilians to attack Makino, who was staying at Kōfūsō, part of the ryokan Itōya in Yugawara with his family. Arriving at 05:45, they stationed 2 men outside, then entered the inn with weapons drawn, at which point policemen stationed inside opened fire, beginning a lengthy gunfight. A policeman notified Makino and his party of the attack, and led them to a rear entrance. The assassins fired upon the group as they left, but did not realize that Makino had managed to escape. Kōno was wounded in the chest during the gunfire, and one policeman, Yoshitaka Minagawa, was killed. As Kōno was carried from the fighting, the assassins set fire to the building. Hearing a single shot, Kōno believed Makino had shot himself inside the burning building. The men took Kōno to a nearby military hospital where all were arrested by the military police.[62][63]

At approximately 10:00, Kurihara and Nakahashi boarded 3 trucks with 60 men and traveled from the Prime Minister's Residence to the offices of the Tokyo Asahi Shimbun, a prominent liberal newspaper. Charging into the building, the officers forced the newspaper employees to evacuate while yelling that the attack was "divine retribution for being an un-Japanese newspaper". They then overturned and scattered the newspaper's type trays (containing 4,000 different characters) on the floor, temporarily preventing the newspaper from publishing.[64]

Following the attack, the men distributed copies of the uprising's manifesto to nearby newspapers and then returned to the Prime Minister's Residence.[65][66]

1st Lt. Motoaki Nakahashi of the 3rd Imperial Guard assembled 120 men and, telling his commanders that they were going to pay their respects at Yasukuni Shrine (or Meiji Jingu, sources differ), marched to Takahashi's personal residence. There he split his men in half and took one group to attack the residence while having the other stand guard outside. After the men smashed their way into the compound, confused servants led Nakahashi and Lt. Kanji Nakajima to Takahashi's bedroom. There Nakahashi shot the sleeping Takahashi with his pistol while Nakajima slashed him with his sword. Takahashi died without waking.[67][68]

Once Takahashi was dead, Nakahashi sent the group that had participated in the attack to join the troops already at the Prime Minister's residence. He then accompanied the remaining group of men onward to the Palace.[69]

Nakahashi and his 75 men entered the palace grounds using the western Hanzō Gate at 06:00. Nakahashi's unit was the scheduled emergency relief company (赴援隊,fuentai?) and he told the commander of the palace guard, Maj. Kentarō Honma, that he had been dispatched to reinforce the gates because of the attacks earlier that morning. Honma had been informed of the attacks, so he found Nakahashi's arrival unsurprising. Nakahashi was assigned to help secure the Sakashita Gate, the main entrance to the grounds directly in front of the Kyūden (the Emperor's residence).[70][71]

Nakahashi's plan had been to secure the Sakashita Gate, then use flashlights to signal the nearby rebel troops at police headquarters to join him. Having gained control over access to the Emperor, the rebels would then be able to prevent anyone but Honjō and others they approved of from seeing him. Nakahashi had difficulty contacting his allies, however, and by 08:00 Honma had learned of his involvement in the uprising. Nakahashi was ordered at gunpoint to leave the palace grounds. He did so, joining Kurihara at the Prime Minister's residence. His soldiers remained at the gate until they were relieved at 13:00, at which point they returned to their barracks. For this reason, these 75 soldiers were not included in the government's official tally of rebel forces.[72][73][74]

120 men from the 3rd Infantry Regiment were led by 1st Lt. Naoshi Sakai to Saitō's private residence in Yotsuya. A group of the soldiers surrounded the policemen on guard and they surrendered. Five men including Sakai entered the residence and found Saitō and his wife Haruko on the second floor in their bedroom. They fired upon Saitō, who fell to the ground dead. His wife covered him with her body and told the soldiers to "Please kill me instead!" They pulled her off and continued to fire at Saitō. Haruko was wounded by a stray bullet.[75]

Following Saitō's death, two officers led a group of men to attack Gen. Watanabe. The rest left to assume a position northeast of the Ministry of War.[76]

Capt. Teruzō Andō led 200 men of the 3rd Infantry Regiment to Suzuki's private residence just across from the Imperial Palace in Kōjimachi. They surrounded and disarmed the police on guard, then a group entered the building. After Suzuki was discovered in his bedroom, he was shot twice (sources differ as to who fired the shots). Andō then moved to deliver a coup de grace with his sword, when Suzuki's wife pleaded to be allowed to do it herself. Believing Suzuki to be mortally wounded, Andō agreed. He apologized to her, explaining that it was done for the sake of the nation. He then ordered his men to salute Suzuki and they left to guard the Miyakezaka junction north of the Ministry of War. Suzuki, although seriously wounded, would survive.[77][78]

Andō had visited Suzuki at his home in 1934 to suggest that Araki be appointed Prime Minister following Saitō's resignation. Suzuki had rejected the suggestion, but Andō had come away with a favorable impression of Suzuki.[79]

Following the attack on Saitō, 20 men led by 2nd Lt. Tarō Takahashi and 2nd Lt. Yutaka Yasuda boarded two trucks and headed to Watanabe's residence in Ogikubo on the outskirts of Tokyo, arriving shortly after 07:00. Despite the two hours that had passed since the other attacks, no attempt had been made to warn Watanabe.[80][81]

As the men attempted to enter the front of the residence, they were fired upon by military policemen stationed inside. Yasuda and another soldier were wounded. The soldiers then forced their way in through the rear entrance, where they encountered Watanabe's wife standing outside their bedroom on the second floor. Shoving her aside, they found Watanabe using a futon for cover. Watanabe opened fire with his pistol, whereupon one of the soldiers fired a burst at him with a light machine gun. Takahashi then rushed forward and stabbed Watanabe with his sword. His nine-year-old daughter Kazuko witnessed his death as she hid behind a table nearby. The soldiers then boarded their trucks and left, taking their two wounded to a hospital, then assuming a position in northern Nagatachō.[82][83]

Capt. Shirō Nonaka took nearly a third of all the rebels' troops, 500 men from the 3rd Infantry Regiment, to attack police headquarters, located directly south of the Imperial Palace, with the goal of securing its communication equipment and preventing the dispatch of the police's "special security force" (特別警備隊,Tokubetsu Keibi-tai?). They met no resistance and soon secured the building, possibly due to a police decision to leave the situation in the hands of the army. The large number of troops involved was because of the intended move on to the palace itself.[84][85]

After the occupation of police headquarters, 2nd Lt. Kinjirō Suzuki led a small group to attack the nearby residence of Fumio Gotō, the Home Minister. Gotō was not home, however, and escaped the attack. This attack appears to have been the result of an independent decision by Suzuki rather than part of the officers' overall plan, however.[86]

The Palace learned of the uprising when Capt. Ichitarō Yamaguchi, a supporter of rebel officers and duty officer for the 1st Infantry Regiment, informed his father-in-law Gen. Shigeru Honjō, the Emperor's chief aide-de-camp and member of the Kōdō-ha, at about 05:00. Honjō then contacted his subordinates and the chief of the military police and headed to the Palace. The Emperor himself learned of the incident at 05:40 and met with Honjō shortly after 06:00. He told Honjō to end the incident, although he was not specific as to how.[87][88]

With Saitō dead and Suzuki gravely wounded, the Emperor's chief remaining advisors were Chief Secretary to the Lord Keeper Kōichi Kido, Minister of the Imperial Household Kurahei Yuasa, and Vice-Grand Chamberlain Tadataka Hirohata. These officials met after learning of the attacks from Suzuki's secretary. They took a hard line, advising the Emperor that he should demand that efforts be concentrated on suppressing the uprising and that he must not accept the resignation of the current government, as doing so would "effectively be granting victory to the rebel army". It was after hearing this advice that Hirohito hardened his position.[89][90]

Kawashima met with the Emperor at 09:30 after his meeting with the rebel officers at the Ministry of War. He read the officers' manifesto and demands aloud and then recommended the Emperor form a new cabinet to "clarify the kokutai, stabilize national life, and fulfill national defense." The Emperor refused and demanded that Kawashima suppress the uprising. When the remaining members of Okada's government, unaware that he was alive, attempted to resign that afternoon, Hirohito told them he would not allow it until the uprising had been suppressed.[91][92]

The Supreme Military Council (SMC) held an unofficial meeting in the afternoon. The meeting was joined by a number of other officers, including Kashii, Yamashita, Kawashima, and Hajime Sugiyama, Vice Chief of Staff. The SMC, while a prestigious part of the army, had little function in peacetime and had therefore become a body to which high-ranking officers could be appointed without actually granting them power. For this reason, by 1936 a number of Kōdō-ha generals, including Araki and Mazaki, had been made members.[93]

The authority of this meeting was disputed; it had not been convened by the Emperor, and Sugiyama argued that it had no authority. Araki countered that the "elders of the army" had a moral obligation to resolve the situation. The Kōdō-ha members and their supporters controlled a clear majority of the council.[94]

Despite the Emperor's order to Kawashima that the uprising be suppressed, Araki proposed that a message be drafted to the rebels. This message, which came to be known as the "Minister of War's Proclamation", has become a point of controversy (it was issued in Kawashima's name because of the unofficial nature of the SMC meeting). Araki and other participants argued later that it had been intended to persuade the officers to surrender. Others interpreted it as an endorsement of the uprising.[95][96]

The proclamation read:

The purpose of your actions has been reported to His Majesty.

We recognize that your motives are based on a sincere desire to clarify the national polity.

The current state of the national polity (including its defilement) is a matter of great regret to us.

All the Supreme War Councilors have agreed to unite and move forward in accordance with the principles stated above.

Once approved, Yamashita brought the message to the rebels in the Ministry of War, who were pleased but somewhat confused by its vagueness. Some of the officers later testified that Yamashita claimed that the Emperor had approved the message, but Yamashita denied this.[100]

Another point of controversy was the proclamation's wording. Although the above text notes that the rebels' "motives" were recognized, another version of the text was distributed by Kashii (possibly at Kawashima's instructions) shortly after 15:30 to military units in Tokyo. This version recognized the rebels' "actions" rather than their "motives". This difference has been attributed to Kōdō-ha manipulation of the text after-the-fact. Araki, Yamashita, and others claimed that what Kashii distributed was an earlier, unfinished draft of the proclamation.[101][102]

Martial Law Headquarters

Two other developments deepened the rebel officers' impression that their uprising had succeeded. At 15:00, shortly before the Minister of War's message was released, Kashii, acting as commander of the Tokyo garrison, ordered a state of "wartime emergency" (戦時警備,senji keibi?) in the 1st Division's operational area (which included the area being occupied by the rebel troops). This had the effect of formally placing the rebel troops within the chain of command under Lt. Gen. Takeo Hori's 3rd Infantry Regiment. Hori placed them under Col. Satoshi Kofuji and charged them with maintaining law and order in their area. Thus, the rebel officers were no longer acting illegally by occupying their positions.[103][104]

As with the earlier Minister of War's Proclamation, this order was later justified as an attempt to convince the rebel officers to end their occupation. The officers were, however, encouraged by the act and convinced that they were on the verge of success.[105]

The second positive development was the declaration of martial law. The cabinet initially opposed this measure as it feared that it would be used to impose military rule (just as the young officers hoped), but they had no choice but to approve it after Kawashima insisted it was necessary to resolve the uprising. The Privy Council concurred, and the edict was signed by the Emperor at 01:20 on the 27th. Kashii was made chief of Martial Law Headquarters. In his first order, issued later that morning, he ordered the rebel troops to enforce martial law in the Kōjimachi area (which they were occupying.)[106]

Despite the above developments, the position of the rebel officers was less secure than it seemed. Most significantly, as noted above, the Emperor and his court officials had taken a hard line towards the uprising. But the rebels also faced important opposition within the military as well, especially from the Army General Staff and navy. Many within the army were pleased by the assassinations because they had removed a number of the army's opponents within the government. However, they could not accept the more radical social ideas included within a "Shōwa Restoration" and were not disposed to accept a Kōdō-ha dominated cabinet. Others, such as Kanji Ishiwara, were infuriated at the rebel officers' use of troops without authorization.[107]

The General Staff was effectively ruled by a triumvirate made up of the Chief of Staff, Vice Chief of Staff, and Inspector General of Military Education. With Watanabe assassinated and the Chief of Staff (Prince Kan'in) ill and away from the capital, Vice Chief of Staff Sugiyama had full control. Sugiyama, a member of the Tōsei-ha, had from the beginning favored the forcible removal of the rebel occupation of the capital. His unwillingness to accept a new cabinet and present a united front with the SMC to the Emperor would ultimately be a major factor in the uprising's collapse. Initially concerned about the uncertainty of the situation, however, he only called in reinforcements from outside Tokyo.[108]

IJN Marines dispatched to Tokyo

The Naval Staff had taken a similarly dim view of the uprising, at least partly due to the attacks on three admirals (Okada, Saitō, and Suzuki). It summoned the 1st Fleet to Tokyo on the 26th. By the afternoon of the 27th, 40 warships were stationed in Tokyo Bay and IJN marines had been dispatched to defend naval installations in the city.[109]

Thus, by the evening of the 26th, the uprising had resulted in a stalemate. The Emperor and Sugiyama's opposition had prevented the achievement of its primary goal: the appointment of a military-centered cabinet centered around Mazaki. Although they had managed to achieve a degree of official recognition for their actions, it was obvious that they could not occupy their positions indefinitely. Their presence was their strongest bargaining chip, but even their supporters felt that it needed to end.[110][111]

It was for this reason that Araki, Mazaki, and most of the other members of the SMC met with Muranaka and Kurihara at the Ministry of War on the night of the 26th. There they congratulated the officers again, but asked that they return to their units and leave the rest to the SMC. The rebel officers, however, convinced of their success, again spoke of the need to promote the Showa Restoration and form a "strong cabinet centered around the military". No agreement was reached. This approach was followed by late-night negotiations at the Imperial Hotel between Ishiwara and Lt. Col. Sakichi Mitsui, a supporter of the uprising. They reached a compromise: a new cabinet under Adm. Eisuke Yamamoto would be appointed and the rebel troops would return to their units. This compromise was rejected by both Sugiyama (who insisted the Emperor would not approve a new cabinet) and the rebel officers (who would only accept a Mazaki cabinet).[112][113]

Finally a settlement seemed to have been reached when the rebel officers asked to see Mazaki on the 27th. Mazaki, accompanied by two other members of the SMC (Nobuyuki Abe and Yoshikazu Nishi) arrived at the Ministry of War at 16:00. Gathered there were all of the rebel officers except Andō and Kurihara, who were in charge of the troops outside, and Kōno, who was still hospitalized. The rebels told Mazaki that they were entrusting everything to him. Mazaki thanked them, but explained that he could do nothing until they returned to their units. He also stated that he would fight them himself if they went against the Emperor's wishes. The rebels replied that if they received a formal order to return, they would of course obey it. Following the meeting, both Mazaki and the rebel officers were relieved. Mazaki believed the rebel officers would leave without violence and the rebels were apparently convinced that a Mazaki cabinet would be formed shortly after they did so. Kashii issued orders for the troops to stay the night in the buildings they had occupied and reported to the Emperor that the situation would be resolved by the morning.[114][115]

However, unknown to Kashii, Mazaki, and the rebel officers, Sugiyama had already asked the Emperor at 08:20 to issue an imperial command authorizing the use of force against the rebel troops. This was immediately granted and issued to Sugiyama, to be released at his discretion. Addressed to Kashii, the command ordered him to quickly evict "the officers and men occupying the Miyakezaka area".[116]

The Emperor had, by the end of the 27th, become increasingly impatient with the failure of the military to suppress the uprising as he had ordered on the previous day. He summoned Honjō throughout the day demanding to know if the rebels had been suppressed. When Honjō spoke in defense of the officers' motives, the Emperor accused them of "trying to pull a silk rope around my neck". At one point, Hirohito became so angry that he threatened to assume personal command of the Imperial Guard and order them to attack the rebels himself.[117][118]

The General Staff and Martial Law HQ decided to release the imperial command at 05:00 on the 28th. From this point on formal documents, which had previously used "uprising", the word chosen by the rebel officers themselves, began to use the word "rebellion" (叛乱,hanran?) instead.[119][120]

At 08:00, the rebel officers' nominal superior Maj. Kofuji was told to inform the officers of the imperial command and order them to return to their units. However, Muranaka and Kōda had already heard of the command from Nakahashi. Believing the order to be a mistake, they went to see him. When they met Kofuji, he only told them to come to 1st Division Headquarters. There they met Gen. Hori, who lied to them, telling them that no command had been issued. The relieved but skeptical officers left.[121]

A meeting of the heads of the army including Kawashima, Kashii, and Sugiyama had been held from the early morning onward (Araki and Mazaki had attempted to attend but had been told to leave as the SMC had no authority). Kawashima and Kashii attempted to convince the group to avoid violence, but when 10:00 passed without any word of movement by the rebel officers, they approved the use of force. However, when Hori and Kofuji came to see Kashii at 10:40, the three agreed that it was too early to enact the imperial command. It has also been suggested that a lack of preparedness on the part of the government forces was another factor. Either way, the action was delayed.[122]

Yamashita visited the Ministry of War at 12:00 and told the rebel officers that the issuance of the imperial command was merely a matter of time and that they should "take responsibility". Hori joined the group at 12:30 and confirmed Yamashita's words. Shortly after, Kurihara, speaking for the group, asked that an Imperial messenger be sent. He said that the officers would commit suicide and the NCOs would take the soldiers back to their barracks. Yamashita, joined by Kawashima, immediately went to the Palace, where he informed Honjō of the request. Honjō asked that the request be granted, but the Emperor refused, saying that they could do it on their own.[123]

Not all the rebels had been prepared to commit suicide. Andō had been infuriated at the idea, yelling that "the generals want to use us as footstools and have us kill ourselves". Andō's rejection of the idea and the Emperor's refusal led to a change of heart among the officers. By 13:30, they had decided to fight. Kofuji learned this at 14:00 when he finally attempted to gather the officers to read them the imperial command and order them to return to their units and they refused (the orders had to be formally given in order to be valid). Soon after, at 16:00, Martial Law HQ announced that force would be used, and the rebel troops were removed from Kofuji's command at 18:00. At 23:00, orders went out to begin preparations at 05:00 on the 29th for a general attack.[124]

I say to enlisted men.
1.Do go back to right now home.
2.Resisting people I shot dead because enemy of the court.
3.Your parents and brother of us are at all sad because you becomes the traitor.

Martial headquarters, February 29.

By the morning of the 29th, the rebel army of less than 1,500 was surrounded by more than 20,000 loyal government troops and 22 tanks. The general attack was planned for 09:00. By 05:30 all civilians in the surrounding areas had been evacuated.[125]

From 08:00 the army began a major propaganda push towards the rebel troops. Three planes scattered leaflets from the air, a giant ad balloon adorned with the words "The Imperial Command has been issued, do not resist the Army colors!" was suspended nearby, and a series of radio broadcasts were made over NHK. The broadcasts and leaflets assured soldiers it was not too late to return to their units and informed them of the imperial command (the broadcasts would cause later problems, for they had promised all crimes would be forgiven). These efforts, together with the hopeless odds, had a devastating effect. Desertions began shortly after midnight; by 10:00, many were gone.[126][127]

Realizing the hopelessness, by noon all the officers except for Andō had released their soldiers. Finally, at 13:00 Andō ordered his men to leave and unsuccessfully attempted suicide by shooting himself in the head. The rest assembled at the Ministry of War. There they met Yamashita and Ishiwara, who suggested that they commit suicide. They allowed the men to keep their sidearms and left. Col. Nobutoki Ide, a member of the General Staff and Nonaka's former commander, came to the building and called for Nonaka to come outside. Shortly afterwards, Nonaka shot himself. Isobe claimed that Nonaka was forced to commit suicide in an attempt to pressure the rest of the officers to do the same. The final rebel officer to commit suicide was Kōno, still hospitalized from the failed attack on Makino, who stabbed himself with a knife a week later. The remaining officers were arrested by the military police at 18:00. They were all stripped of their ranks.[128][129]

The Emperor signed an ordinance on March 4 establishing a Special Court Martial (特設軍法会議,tokusetsu gunpō kaigi?) to try those involved in the uprising. All 1,483 members of the Righteous Army were interrogated, but ultimately only 124 were prosecuted: 19 officers, 73 NCOs, 19 soldiers, and 10 civilians. Of these, all of the officers, 43 NCOs, 3 soldiers, and all of the civilians were found guilty. The trials related to the uprising took nearly 18 months to complete.[130]

The main trial of the ringleaders of the rebellion (the 19 surviving officers, Isobe, Muranaka, and 2 other civilians) began on April 28. The trial was held in secret, and the defendants did not have rights to legal representation, call witnesses, or appeal. The judges were not interested in hearing about the defendants' motives and intentions, and forced them to concentrate on their actions in their testimony. The trial was therefore far different from the ordinary court martial that Aizawa had faced a few months earlier. Charged with rebellion (反乱罪,hanran-zai?), the rebel officers argued that their actions had been approved by the Minister of War's Proclamation and their incorporation into the martial law forces, and that they had never been formally presented with the imperial command. The verdicts were handed down on June 4 and the sentences on July 5: all were found guilty and 17 were sentenced to death.[131][132]

Four more trials took place for those directly involved in the attacks: one for those NCOs involved in the attacks on Saitō, Watanabe, and police headquarters; one for those NCOs involved in the attacks on Okada, Takahashi, Suzuki, and the Ministry of War; one for the soldiers involved in those attacks; one for the NCO and 6 civilians involved in the attack on Makino. A series of trials were also held for 37 men charged with indirectly supporting the rebellion. 24 were found guilty, with punishments ranging from life imprisonment to a fine of 45 yen. The most noteworthy of these were Ichitarō Yamaguchi (life imprisonment), Ryu Saitō (5 years), and Sakichi Mitsui (3 years).[133]

Ikki Kita and Mitsugi Nishida were also charged as ringleaders of the rebellion and tried in a separate trial. Their actions during the uprising had only been indirect (primarily providing support over the telephone) and as such, they did not actually meet the requirements of the charge. The chief judge, Maj. Gen. Isao Yoshida, protested to the Ministry of War that the charges were improper. However, the Tōsei-ha generals now dominant in the army had decided that the two men's influence had to be eliminated; Yoshida later wrote another judge to tell him that regardless of the lack of evidence, it had been decided that the two must die. They were sentenced to death on August 14, 1937.[134][135]

The only significant military figure to be tried for their involvement in the uprising was Mazaki, charged with collaborating with the rebel officers. Although his own testimony showed him to be guilty of the charge, Mazaki was found not guilty on September 25, 1937. This result has been attributed to the influence of Fumimaro Konoe, who had become prime minister in June.[136][137]

15 of the officers were executed by firing squad on July 15 at a military prison in Shibuya. The execution of Muranaka and Isobe was delayed so that they could testify at Kita and Nishida's trial. Muranaka, Isobe, Kita, and Nishida were executed by firing squad at the same location on August 14, 1937.[138]

Despite the failure of the coup, the February 26th Incident had the effect of significantly increasing the military's influence over the civilian government. The Okada cabinet resigned on March 9 and a new cabinet was formed by Kōki Hirota, Okada's foreign minister. This transition was not without its problems, however. When the selection of Hirota was made clear and efforts began to assemble a cabinet, Gen. Hisaichi Terauchi, the new cabinet's Minister of War, made his displeasure with some of the selections clear. Hirota gave in to Terauchi's demands and changed his selections, choosing Hachirō Arita over Shigeru Yoshida as Minister of Foreign Affairs, for example.[139]

This interference with cabinet selection was followed by a demand that only active-duty officers be allowed to serve as Minister of War and Minister of the Navy. Until this point, reserve and retired officers had been allowed to serve in these positions. This demand was accepted and authorized by imperial commands on May 18. This change would have far-reaching implications for the Japanese government, as it effectively gave veto power over government policies to the military services. By asking a minister to resign and refusing to appoint a new officer to serve as his replacement, the services could cause a government to fall at their pleasure. This fate would, in fact, meet Hirota less than a year later when Terauchi resigned over Hirota's refusal to dissolve the Diet.[140][141]

Although only Mazaki faced criminal charges, this didn't mean that the Kōdō-ha didn't suffer any consequences from the incident. Under Terauchi's auspices, "reform staff officers" (革新幕僚,kakushin bakuryō?), most notably Ishiwara and Akira Mutō, began a purge of the military. Of the 12 full generals in the Army, 9 were removed from active service by the end of April, including Kōdō-ha members Araki, Mazaki, Kawashima, and Honjō. At the same time, other Kōdō-ha officers and their supporters were either removed from active service or sent to positions away from the capital where they would be less able to influence policy. Among these were Yamashita, Kashii, Kofuji, Hori, Hashimoto, and Yanagawa. Although other, non-Kōdō-ha officers were also targeted to a limited extent, the focus of the actions was clearly on eliminating Kōdō-ha influence. Almost every high-ranking officer who had helped support the rebels during the uprising was therefore affected.[142]

The parents, widows, and children of the executed men, who were prevented by the government from commemorating them until the end of the war, formed the Busshinkai (佛心会?). They have established two sites in Tokyo commemorating the officers of the February 26th Incident.[143]

In 1952, shortly after the end of the Allied occupation of Japan, they placed a gravestone entitled "Grave of the Twenty-two Samurai" (二十二士之墓,nijūni-shi no haka?) in Kensōji, a temple in Azabu-Jūban, where the ashes of the executed men had been placed. The "twenty-two" signifies the nineteen men executed, the two who committed suicide (Nonaka and Kōno), and Aizawa.[144]

Then, in 1965, they placed a statue of Kannon, the Buddhist goddess of mercy, dedicated to the memories of the rebel officers and their victims at the former location of the Shibuya execution grounds.[145]
